Application filed October 24, 1921. Serial No. 510,043.

To all whom it may concern:

Be it known that I, DENIS J. OSULLIVAN, a citizen of the United States, and a. resident of Home, county of Oneida, State of New York, have invented certain new and useful Improvements in Combination Locks, of which the following is a specification.

This invention relates to combination locks, principally for locking railway car doors. The door is locked by an ordinary hook latch, the same being hooked firmly inside a chamber which is provided with a door, and which in turn is locked by the combination lock.

The object of this invention is to provide a new and novel means of the combination type for locking the door of a chamber in which the primary locking of the principle element is accomplished.

A further object is to provide a lock of the combination type, whereby the key parts for manipulating the combination may be removed, and any one desiring to open the lock must have a key or keys in addition to knowing the index numbers for opening the same.

In conjunction with the above stated ob jects a further object is to provide a lock which can be pre-arranged by the man who does the locking, in that the mode or procedure of following out the index numbers of the combination for manipulating the lock may be changed; and also a lock in which the mechanism as a whole can readily be taken out of the chamber and a new one substituted therefor, in the event that the same becomes dis-arranged or gets out of order.

' This invention will be more fully understood and other objects will be apparent, from the following description taken in connection with the accompanying drawings, forming a part hereof, and in which similar numerals refer to similar parts throughout the several views. I

Fig. 1, represents the lock arranged in combination with a freight car door.

Figs. 2 and 3 are keys for manipulating the lock.v

*ig. 7, shows the inside of the chamber; the doors 1 and 2 being removed.

F 1g. 8, is a perspective view of a portion of the lock.

Fig. 9, is a sectional view taken on line 9-9 of Fig. 4.

Fig. 10, shows theinside of the chamber, the doors land 2 being removed, and the locking mechanism in a different position from that shown in Fig. 7.

Referring to the drawings, 3 is a portion of the side wall of a freight car. 4 is a portion of the car door; the same being mount-- ed on rollers and free to slide in the usual manner. 5 is a door latch, pivoted to the door 4 as shown at 7, Fig. 1. The locking mechanism 8, Fig.1also shown enlarged in Figs. 7 and 10is fitted in the chamber 9 as shown. The door 1 is carried by the hinges 10 and the door 2 by the hinges 11. The door 1 is held closed by the latch shown in Fig. 5, in which 12 is a U shaped block substantially forming a part of the wall 14:, and 15 is a block substantially forming a part of the door 1 and carries the swivel hook 16. It is obvious that by giving the swivel hook 16 one-quarter turn, the door 1 can be opened. Access to the latch shown in Fig. 5 can be had only when the door 2 is open. v

Fitted in the bottom of the chamber 9 is a base plate 17 the same beiiig tree to slide and guided by the tongue and groove shown at 18. Carried by the base plate 17 is a plate 20 which is free to slide and is guided by projections 21 and 22 of the base plate 17. The plate 20 is provided with "four slots 23 into which engages lock strips 24 when the locking element 19 is down as shown in Figs. 9 and 10. The sliding plate 20 is further provided with a notch 25 into, which engages the latch 26, the same being carried by the door 2 as shown in Fig. 6. The latch 26 ,is pivo'ted on the pin 27, and adaptable to engage with the slidingplate 20, and lock the'doorQ closed a's's'hown in Fig. 9'.

fbyi'fthe base" plate 17i'are four standards 28 which carry the top plate 29. Forming a part of the standards 28 are projecting lugs 39 which project through open ings in the plates 29 as shown. Through holes in the projecting lugs 30 are fitted pins 31 which must be removed when it is desired to remove the plates 29. Between the standards 28 are a series of partitions 3'2 which form compartments 33. Into these compart ments are fitted locking levers 34. The looking levers 34 are pivoted on the pins 37, and the ends thereof project above the plates 29 through openings 35 as shown.

Pivoted on the lower ends of the locking levers 34 are locking blocks'36, which are so arranged that when the locking levers 34 are turned to the proper posit-ion on the pivot pins 37. the locking blocks 36 may be positioned through the slots 33, and into the channels 43, thereby preventing thehinged element 19 from being opened to the position shown in Fig. 7.

By examining Fig. 9, wherein the locking blocks 36 are positioned to engage through the slots 38 and into the channels 43,:it is obvious that the locking blocks 36 might be changed to the position indicated by dotted lines at 36' they would then be positioned to engage through the slots 38 into the opening 42, and in this manner lock the hinged element 19 from being opened. The object of this, is .that the man who looks the car door may arrange the locking blocks 36 to suit hisown choice,.some to the right and some to'the left, and no one except himself knows which direction the locking levers 34 must be moved to release the hinged element 19 from the locked condition. He of course makes a record of how he has arranged these looking elements and forwards the same to the man who is permitted to open the lock.

The side plates 39 are pivoted to the base plate 17 at the point 40, so that they can be swung outward to observe the condition of the locking blocks 36. The center beam 41 forms a part of the base plate 17 and is provided withan opening 42 into which fit thelocking blocks 36. The side strips 39 are each provided with a hole 44 which engages the pins 45; these pins being carried by hinged element 19, holds the side'plates 39 in vertical position when the hinged .element 19 is down.

Carried by the hinged element 19 are standards 46 which carry the rods 47 they form guides upon which is mounted cross head 48 inamanner free to slide in either direction, indicated by arrow 50. Carried by the cross head 48 is a sliding block 51 mounted in a manner free to slide in either direction indicated by arrow 52. Forming a. part of the sliding block 51 are projecting lugs 54 which are adaptedto engage with the end 55 of any of the locking levers 34.

Through the manipulation of the sliding block 51, the locking blocks 36 may be positioned through. the locking levers 34 and the lugs 54 to lock the hinged element 19 down through the locking levers 34 and the lugs 54. r

The cross head 48 is provided with an opening 56 adapted to receive a key 57. Fig. 2, represents a perspective view of the key 57, the same being constructed of a flat strip 58 which is provided with a lug 59 and an opening 60; the strip 61 is provided with an opening62 which engages the lug 59. The opening 60 engages wlth the lug 63 of sliding block 51, as shown in Fig. 9, and thereby the sliding block 51 can be manipulated for positioning the locking block 36.

The door Qisprovided with an opening 64 through which the key 57 maybe inserted inthe cross head 48. A sliding block 65 is carried by theguide strip 66 forming a part of the door 2; it is also provided with an opening 67 throu 'h which the key 57 is placed, and is carrier with any move ment of the key .57 in the direction indicated by the arrow 68. .The block 65 is further provided with a pointer 69, and the guide strip 66 is stamped with index numbers 1 to 10 as shown. The object of the index numbers, is to guide the operator in locating the cross head 48 so that the lugs 54 will engage with the ends v55 of the levers-34.

The method of manipulating this look is as follows :--First assume that the operator desires to lock the carand :prearrange the combination foropening the same to suit his own choice; the car door is locked in'the ordinary manner by the hook latch "5, the same engaging with the block. 70 which prevents the car door from being opened from the outside. The locking mechanism is removed from the compartment 9 and the hinged element 19 is removed from the base plate 17 by taking out the pin 71.; then he removes the pins 31; takes oif the plates 29 and pulls out the pivot pins 37. He then arranges thelooking blocks 36 relative to the locking levers 34 to suit his own choice, and re-assembles the device as shown in Fig. 8. The hinged element 19 is then replaced and the complete locking mechanism is again placed in the compartment 9. The door 1 is then closed and latched by the latch shown in F ig. 5; the door 2- is closed and the latch '26 is caused to engage with the sliding plate 20 as shown in Fig. The hinged element 19, is then lowered to its full extent as shown in Fig. 10, the same being accomplished by inserting the flat portion 74 of the key shown in Fig. 3 through the aperture 7 2 in the door-2,.and into the open- :ing 75 of the hinged element 19. When the hinged element 19 is lowered to its full extent, the key 57 is inserted through the sliding block 65 and into the cross head i8; the parts 58 and 61 being arranged and associated in conjuction with the cross head 48 and the lugs 63 as shown in Fig. 9. The procedure of locking the hinged element 19 in its down position, is by manipulating the key 57, moving the same in the direction indicated by the arrow 68, stopping the pointer 69 at each of the indexed members 1 to 10, and moving the key 57 in or out as indicated by the arrow 52. and as re quiredfor positioning the looking blocks 36 for locking the hinged element 19 down. The keys 57 and 7e are then removed and the lock operation is complete. I v

The, operation for unlocking the lock is accomplished in substantially the same manner,;eXcept that the locking levers 34: are moved in the proper position for disengaging the locking blocks 36 through the slots 38 and 38.

The man who receives the car is provided with duplicate keys like that shown in Figs.

' 2 and 3, and is also provided with a record of the locking combinatio by the man who did the locking; this wi 1 enable him to open the lock.

I herein show and describe 20 looking levers 34, but it is obvious that this number may be more or less, the difference being, only in that a greater or less number of different combinations can be had.

To prevent the hook 5 from becoming disengaged with the locking blocks 70 through vibration from the bumping of the train; I provide a block 7 6, which is pivoted at 77 to the bracket 78, the same being carried by the side wall 14 of the chamber 9. By eX- amining Figs. 7 and 10 it will be obvious that the hook 5 cannot be disengaged from the locking blocks 70 unless the block 76 is given a quarter turn on the pivot pin 77.

This whole mechanism is so arranged that access to the hook 5 and the block 76 cannot be had except when the door 1, or 2 is opened. I have herein shown and described this look as being applicable for locking railway car doors, but it is obvious however that the same may be used for locking anything of the character whereby it can be accomplished by inclosing a hook or locking element in a chamber; or the chamber 9 might be made large and be empolyed as the safe deposit chamber for securing valuable articles.
